Electric heater is relatively wide application range in life, and below will give you a simple introduction to its application in the plastics industry. 1, metal cast electrical heater: is a heat generating body with a metal tubular electric heat element. According to the specifications of the heaters, bending molding, entering mold production, cast aluminum, cast copper, cast iron heating body. This product is currently the ideal product of the current plastic industry. This product has a rapid temperature. Heating is good, well-thermally conductive, long service life. According to the user needs, the surface load of the cast heater is 2.5 ~ 3.5 w / cm2. The surface load of the cast copper cast iron heater is 4.0 ~ 6.0 w / cm2. Special specifications can be processed according to drawings. 2, metal mica electric heater: is a heating wire with a high medium nickel portable heater 锘 2080 alloy. The mica or artificial mica plate is used to wind. The outer layer uses a different metal plate according to the user as a heating ring, machined, and a heating ring such as a heating ring, a plate, and the like. The surface load normal power should be from 2.5 to 3W / cm2. The customer can use the automatic temperature control system to ensure the service life of the heater according to the required heating temperature. 3, tubular electric heat element (metal tubular heater): metal tubular heater is a metal housing (titanium steel, stainless steel, carbon steel, copper, etc.), and internal nickel-free welded wire . The voltage power resistance of the required required by the heat generator. Evenly distributed tube inner gap filling high purity battery, the insulated thermal conductivity is better than the magnesium oxide tube, using a shrinking furnace, a hot spot furnace, a drying equipment, a hot press forming, a food machinery, a barbecue, and a household appliances such as electric heating machine. The above is the application of electric heater in the plastic industry. I hope that the above explanations are helpful to everyone. If you have more knowledge you want to know, welcome to contact us.
